Description

[0001] The invention relates to a chamber for hardening building materials, wherein the chamber consists of mutually insulated sheet metal elements mounted on a base plate, which form walls and a ceiling.

[0002] Such chambers are already known for drying bricks. Chambers for curing concrete blocks feature shelving systems consisting of several shelf supports and several support elements arranged on the shelf supports to support the shelves on which the concrete masses to be cured are stored. Air, controlled in temperature and humidity, is piped to the concrete masses to be cured. The supply air pipe system can sometimes be integrated into the shelving system. Another, complex exhaust air pipe system, which can also be partially integrated into the shelving system, serves to ensure appropriate airflow.

[0003] US patent specification US 5,079,855 discloses a chamber. Furthermore, US 2005 / 0133016 A1 discloses a chamber according to the preamble of claim 1.

[0004] The invention is based on the object of demonstrating a cost-effective alternative curing chamber suitable for both concrete blocks and CO2-curing building materials.

[0005] The problem is solved by the subject matter of patent claim 1.

[0006] The stressed, self-supporting sheet metal elements eliminate the need for complex shelving systems. The double-walled design of the sheet metal elements significantly simplifies and reduces the cost of gas supply and gas removal.

[0007] It is worth imitating that the walls and / or ceiling are self-supporting and formed from several trough-shaped sheet metal elements, which consist of a base area, side walls bent on all sides and edge strips bent inwards relative to these, running essentially parallel to the base area, wherein sheet metal panels forming the interior of the thus formed double walls and / or double ceilings of the chamber are arranged in a substantially gas-tight manner on the edge strips, so that the edge joints are firmly and essentially gas-tightly connected to one another, in which sheet metal elements with their base area in a common plane are held together by their side walls via gaskets bracing connections, while sheet metal elements adjoining at right angles are held by side walls via gaskets with edge strips and bracing connections arranged thereon,The double walls and / or double ceilings have a media inlet and / or media outlet, with the metal panels having media inlets and / or outlets directed into the chamber. In addition, support elements are screwed, welded, or suspended from the edge strips, which serve to support beams for the building materials.

[0008] According to a first embodiment, it has proven useful to ensure tightness and stability that the connections of the joints of the side walls and the edge strips of the trough-shaped sheet metal elements are formed by a weld seam.

[0009] It is advisable to use self-adhesive sealing strips and / or pasty sealants as seals, either circumferentially or continuously. If, for example, silicone is used as a pasty sealant, subsequent insulation can be added without having to worry about damaging the sealing strips during assembly of the chamber.

[0010] In order to ensure that the ceiling can be walked on without any problems, it is advisable that trough-shaped sheet metal elements and / or sheet metal panels intended for ceilings are made of sheet metal of a higher thickness and / or a material of higher strength and / or have wider side walls and / or edge strips than the trough-shaped sheet metal elements and / or sheet metal panels intended for walls.

[0011] For thermal insulation of the outer walls of the chamber, it is proposed that walls formed by base areas of trough-shaped sheet metal elements be assigned claddings provided at intervals corresponding to the thickness of insulation packs, whereby the cladding can be made of trapezoidal sheet metal.

[0012] For thermal insulation of the ceiling, it has proven effective to assign claddings to the ceiling formed by the base areas of trough-shaped sheet metal elements at intervals corresponding to the thickness of horizontal insulation layers, whereby perforated sheets can be provided as cladding.

[0013] For thermal insulation of the sheet metal elements from each other, it is advantageous that the spaces formed between the base surfaces of the trough-shaped sheet metal elements opposite one another or between the base surfaces of the trough-shaped sheet metal elements and the cladding are filled with pourable insulating material and / or insulating panels.

[0014] The features of the invention are explained in detail with reference to the description of an exemplary embodiment in conjunction with the drawings illustrating the same. In the drawings: Fig. 1 shows a broken-off chamber according to the invention, Fig. 2 shows a partially sectioned section of the chamber according to the invention in side view, Fig. 3 shows a section of the chamber according to the invention in perspective view, Fig. 4 shows a double-walled sheet metal element, and Fig. 5 shows a section of a wall.

[0015] In Figure 11 shows a partially broken-off chamber 1 according to the invention, which has walls 2 and a ceiling 3. The walls 2 consist of a plurality of double-walled sheet metal elements 4, which are screwed together, for example, and stand on a base plate 5. At the upper end, the upright double-walled sheet metal elements 4 of a wall 2 are connected to a media inlet 6, in this case a pipe system, which feeds the individual double-walled sheet metal elements 4 with a gaseous medium. An opposite wall 2' is connected to a media outlet 7, through which the gaseous medium can be sucked off. This can create a gas flow between opposite walls, which serves to harden the building materials.

[0016] Each double-walled sheet metal element 4 consists of a trough-shaped sheet metal element 8 with bent side walls on all sides and edge strips 9 bent inward relative to these, running essentially parallel to the base of the trough-shaped sheet metal element 8. The joints of the side walls and edge strips 9 of the trough-shaped sheet metal elements 8 are connected to each other in a gas-tight manner by a weld seam. This weld seam also increases the stability of each individual trough-shaped sheet metal element 8.

[0017] Support elements 10 are screwed, welded, or suspended from the edge strips 9. The support elements 10 serve to support supports (not shown) for the building materials. The edge strips 9 are designed so large that metal panels 11 are screwed in a substantially gas-tight manner between the docking points for the support elements 10 on one side of each trough-shaped sheet metal element 8 and the docking points for the support elements 10 on the opposite side of each trough-shaped sheet metal element 8. The sheet metal panels 11, which are located behind the support elements, have openings, holes, or nozzles through which the building materials can be specifically sprayed with gas or through which the gas is sucked back into the double-walled sheet metal panels, depending on whether the double-walled sheet metal elements 4 are connected to a media inlet 6 or a media outlet 7.

[0018] Chamber 1 has several doors 12 through which the filling for chamber 1 can be introduced. Double-walled sheet metal elements 13 are also provided on the ceiling 3. For fall protection, the chamber has a railing 14 on the ceiling 3.

[0019] In Figure 2 On the base plate 5, erected walls 2 can be seen, whereby the Figure 2 The wall 2 arranged on the left is an outer wall consisting of a trapezoidal sheet 15, an insulation 16 and the double-walled sheet elements 4. The inner walls consist of the double-walled sheet elements 4, an insulation 16 and the adjoining double-walled sheet elements 4. At the upper end of Figure 2It can be seen that the double-walled sheet metal elements 4 are connected to media inlets 6 and media outlets 7. The double-walled sheet metal elements 4 each consist of a trough-shaped sheet metal element 8 with C-shaped bent edges, with the sheet metal panels 11 being placed on the respective edge strips 9 of the trough-shaped sheet metal elements 8. Furthermore, the edge strips 9 hold the support elements 10.

[0020] In Figure 3 is a corresponding perspective section according to Figure 2 Here, too, the trough-shaped elements 8, the metal sheets 11, and the support elements 10 can be seen. The insulation 16 is also shown in each case.

[0021] At the upper end of the walls 2, the double-walled sheet metal elements are provided with media inlets 6 and media outlets 7. In this case, it is possible that not every double-walled sheet metal element 4 of a wall 2 is equipped with a connection for the gas, but rather that, for example, only every second double-walled sheet metal element 4 is supplied with corresponding gases or that gases are only extracted through every second double-walled sheet metal element 4. In this case, an offset of one double-walled sheet metal element 4 can be provided between the media inlet 6 on one side and the media outlet 7 on the other side, for example, so that the gases flow diagonally through the chamber 1 from a media inlet 6 to the offset media outlet 7.

[0022] Figure 4shows a double-walled sheet metal element 4 consisting of a trough-shaped sheet metal element 8 into whose edge strips 9 support elements 10 are suspended. The trough-shaped sheet metal element 8 is closed by the sheet metal panel 11. The media inlet 6 and media outlet 7 are shown in the upper area of ​​the sheet metal panel 11. The sheet metal panel 11 has a large number of openings as media inlets 17 and media outlets 18, through which the gas can flow to the building materials or through which the gas can be sucked into the double-walled sheet metal elements 4.

[0023] Figure 5 shows several interconnected double-walled sheet metal elements 4 of a wall 2. Here, the support elements 10 suspended in the edge strips 9 as well as the sheet metal panels 11 with their media inlets 17 or media outlets 18 can be seen. Reference symbols overview
